To all 'whom it may concern citizen of the United States, residing at Jacksonport, in the county of Door and v y p are denotel by like characters of reference.

State of Viisconsin, have invented new and usefulmprovementsin Flows, of which the but-fthe mold board consists ofan-angular following is a specification. f

rl`hi`s invention relates to plows, and it has particular reference to plows for deep tilling. Vvhen'V deep plowing is vperformed with a plow of ordinaryl construction, the entire slice is. turned over and the soil which yis brought to the surface is frequently less rich and desirable than the top soil, thus necesisitating replowing in order thaty the best results may be attained.

The invention has for its object to providey a plow of improved construction whereby the bottom portion of the slice turned by the plow will be loosened and broken up in the process of plowing and sifted back into the furrow, only the upper or top portion of the slice beingactually turned, thereby attain@ ing all the beneficial results of deep plowing with none of the disadvantages.

A further object of the invention is to produce a simple and improved plow structure having an angular or recessed mold board provided with means for breaking up and pulverizing the bottom portion of the slice and permitting it to sift back into the furrow and vother means whereby the top portion of the slice will be turned, thereby exposing that portion of the soil containing the rich humates and plant food. v

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation' is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modificati'ons within the scope of the claim may be resorted to when desired.

In the drawing, Figure '1 'is a perspective view of a plow constructed in accordance with the invention. Fig. 2 is a rear view of the same. Fig. 3 is a detail view showing the mold board detached. Fig. 4 is a detail Specification ofLetters llatent; i

turning wing or ,leaf detached.

Corresponding parts in the several figures The-share i15`is of ordinary construction,

member 16 whichinv the ldrawing has been being understood that in a left hand plow the mold Jboard will be substantially L- i shaped. Theniold [board v16 is? connected with the share 15 in any ordinary and well known manner. l Y

.Secured on the rear facevof the base of the mold boardv adjacent to the upper edge of said base is 'a plate or bar 17 havingY rearwardly extending lingers 18 of Which any desiredv number may be used, and said lingers being curved or appropriately formed for the purpose in View. The plateor bar 17, together with the fingers 18, constitutes what may be termeda sifting member, the

purpose of which is'to break and pulverize a portion of the slice that is being turned by the plow and to permit thepulverized soil to drop back intoy the-furrow. Similarly secured to the shankV or upwardly extending portion of the mold board near the upper end thereof is a rearwardly extending wing 19, said wing being attached to the rear face ofthe shank of the mold board, and said wing extending upwardly and rearwardly and having. a curvature which is found suitable to turn that portion of the slice which isnot broken up and sifted back into the furrow.

For the purpose of assembling the sifting member, as well as the wing, with the mold board, bolts orother suitable fasteningmeans may be utilized, as indicated at 20. It is desired to be understood that the dimensions of the wing 19, the number of vsifting teeth employed and the curvature of the y*several parts may be varied to produce the best results according to the nature of the soil that is to be operated upon.

It will be readily understood that in the use of this improved plow the soil may be tilled to any desired depth, deep plowing being necessary especially in dry regions where it is highly important that the water precipitated be conserved to the utmost. It

deep plowing where the entire slice is turned, the soil conditions are frequently such that an undesirable stratum of the soil will be ex-Y posedV when the entire slice is turned. Replowing is thus frequently rendered necessary in order to expose a suitable seed bed. By the present improvement the soil may be tilled as deep as Vmay be desired, and the sifting ngersmay be arranged andproportioned in such amanner as to cause any desired proportion of the slice to bebroken up Y and pulveri'zed and permitted to sift between Having thus described the invention, what is claimed as new, is

In a plow having a beam, a standard and share of'ordinary construction, an angular substantially L-shaped mold board mounted above and adjacent to the share and comprising a base portion and an upwardly extending shank portion, in combination with a sifting member consisting of a plate secured on the'rear face of the base portion and having rearwardly extending ngers, and a wing secured on the rear face of the upwardly extending shank portion, said wing extending laterally above the fingers of the sifting member.

In testimony whereof I affix my signature' in presence of two witnesses;

- GEORGE F. BUTLER.
